T0 (0 whom 712; may concern.-

Be it known that .11, {ions II. VINTON, of Boston, county of Suffolk,and State of Massachusetts, have invented an Improvement inButton-Setting lllachines, of which the following dcscriptioininconnection with the accompanying drawings, is a specification, likeletters on the drawings i-cprosentin g like parts.

This invention has :l'or its object to improve the construction of thatclass of machines represented in United States Patent No. 312,987, datedFebruary 2-1;, i685,especially in the construction of the mechanism tocontrol the passage of the staples and attmilunl buttons, one at atiine,l'rom the stai ilo-ehute into the guide of the staple-carrier. lhave also provided the carrier with a saddle tor the logs of the staple,and with a spring to act aginst the end of the shank or eye of thelu'itton and arrest or hold it midway the said guidr until acted upon bythe driver or former.

Figure 1, in side elevation partially broken out,rcprcsents a sullicientportion of a buttonsetting apparatus of the class referred to to enablemyinvention to he understood, the carrierand driver being shown asdescendiug,the driver being just ready to force the staple from thecarrier into the material. Fig. 2 is an inside elevation of the carrieralone; Fig. 3, a button and staple attacl1ed,ready to be placed in thestaple-guide; Illig. 4-, a dot ail of the driver or 'l'ormcr alone; .lig. 5, a top view of the staple-holding tube and part 01' the chute.Fig.6 is a detail of the hi cti on device removed, and Fig. 7 is across-section of Figs. 1 and 5 in the dotted lines 1 7 The main orstationary Iranie-work A, the anvil c, the horn A, the rod D, itsattached arm D the driver mand the carrier, to be referred to, aresubstantially as represented in the patent referred to.

The staplechutell"s connected with a plate, 1%,attz'tchcd to the i'r;.vork by screws 22.

The slide-bar d, to which the slot-led guide (I attached, the said barand guide constituting the carrier, is guided in the hearing or box A ofthe frame-work A, and in the bean ings 57 and 59 ofthe arm I).

The spindle 23, attached to the upper end of the bar (1, is extendedthrough a spiral spring, 21-, then through the hearing or box 59 of thearm D and the friction device 60 thereon, and thence through a spiralspring, 25, above which the spindle is provided with a check-nut, 26,the spring 25 acting normally to lift the carrier, and the spring 2-l topermit it to be depressed in a yielding manner to enable the lower endof the carrier to strike against the material on the anvil in advance ofthe contact of the lower end of the driver or former with the head orcrown of the staple to be driven, the carrier when arrested by thematerial on the anvil stoppi ng,\\'hile the driver or former continuesto descend to drive the staple from the carrier.

in accordance with my invention I have provided the lower end ol' theslide-ba1.(l', within the carrier and opposite the open end of thestaple-chute B, with a saddle-piece, 27, astride of which the staple swill land as it leaves the chute B and enters the carrier, the saidstaple descending in the said carrier with its legs properlydircelinldownward,and with the center of the crown of the staple in theeye of the button I), the staple hanging vertically.

Below the saddle I have provided the slidebar with a button-holdingspring or prcsser, 28,which acts against the end of the eycof the buttona little below the center of the button, thus checking or holding thebutton in the slot of the carrier midway thereof, while the latterdescends to place its lower end against the materiahand while the driveror former is descending to strike the staple.

The staples 3, having buttons 0 attached, are preferably first fed byhand into a tube, T, which may be readily attached to the upper end ofthe chute ll in position to let the staplcs pass freely into thestaple-chute ii, the said staples, with attached buttons, sliding downthe staple-chute until the shank of the button comes in contact with thedetent M, pivoted at 3i, and acted upon by a. spring, 32, the latternormally keeping the point of the detent in the slot of the chute 15.

A let-oil, L, is pivoted at 8t on an car, 35, of the plate B a spring,36, acting on the letofl, normally keeping its point in the slot of thestaple-chute below the said detent.

The drawings show but one staple and atiached button as held by thedetent, another staple and button having passed the detent and beingheld by the let-off, while a third 5 staple is shown as within the guideof the staple-carrier, the button being outside the said guide.

The arm I) has an car, 37, provided with a projection, preferably anadjustable screw,

: 38, which, during the descent of the said arm from its position, Fig.l, which is nearly its lowest position, strikes the projection 33 of thelet-off L, turns it, and permits the staple held by it and its attachedbutton to slide down the staple-chute; but at this time it will benoticed that the driver 6 is in the carrier and about to drive thestaple therefrom, and that the said driver then acts to close theopening through which the staple must pass :0 to enter the carrier fromthe end of the chute.

Just as the let-off is operated to permit the staple held by it todescend by gravity in the staple-chute, the driver or former 6 acts todrive the staple under it from the carrier in and through the materialsupported on the anvil a, thus clinching the points of the sta ple.

After the staple has been driven and clinched the arm I) is raised, andwith it the 50 driver 0, and the carrier is lifted until the upper endof the guide (I meets the boX or hearing A" of the rigid arm of theframe-work, after which, in the further ascent of the said arm D thespring is compressed, and

55 while the said guide d remains at rest the driver or former is raisedsufficiently to uncover the end of the staple-chute B and the entranceinto the carrier-guide, and during the yet further ascent of the arm Dand the to lug 37 the latter strikes the pivoted block of the detent M,lilting it in the direction of the arrow thereon, but without turningthe detent M on its pivot.

In practice the end of the car 37 passes 5 above the portion 30 of thedetent M, and when the arm D is again depressed the said ear strikes theblock 30 and turns the detent before the screw or projection 38 meetsthe let-oil" L, such movement of the detent during the descent of thearm D permitting the button held by the detent to descend against thelet-oft, which holds the staple and button-eye above it until in thefurther descent of the arm D the projection 38 strikes the portion 33 ofthe let-oll', the movement of the latter permitting the staple andbutton held by it to pass the let-oil and slide down the chute againstthe driver.

The saddle 27 may be a separate piece, as

53 shown, or be integral with the spring 28.

The tubes T (a number of which are employed with each machine) may befilled and kept ready to be applied to the upper end of the chute 13, afilled tube being applied to 55 the chute whenever necessary. The tube Tis slotted from end to end at its lower side,

(see Fig. 7 and has at its ends spring steps or catches it, portions ofwhich normally enter notches in the tubes and act to retain. the staplesin the tubes while the latter are being handled.

The spring t has a projecting finger, 58, which as the tube T is appliedto the open upper end of the chute I3 rides upon the cam 39 at the upperend of the detent, as in Fig. 1, the said cam lifting the spring andremoving its lip or projection 40 from the tube, permitting the staplesand buttons to readily pass into the chute, one staple and button beingshown by dotted lines.

The friction device 60, made as a slotted block held in place by thebearing 59, may be made to pinch the rod 23 more or less snugly byturning the adjusting device (Shown as a screw, see Figs. 1 and 6.) Thisfriction device may be made to pinch the rod sufficiently close toenable the latter by the I friction device to travel in unison with thearm I) as it rises and falls, so long as the movement of the carrier isnot arrested by some device not a part of the said arm D as, forinstance, when in the descent of the arm D the lower end of the carriermeets the material 011 the anvil the carrier is stopped, and thereafterthe arm I) and the friction device slides down upon therod 23, and itslides upward on the said rod after the carrier, in its upward movementwith the said arm Dflstrikes the box A*.

The hinged block 30 prevents the turning of the detent as the driverrises, and obviates accidental forcing of the staple above it andlessens the liability of getting two staples and buttons at one time inthe guide.

I claim 1. The chute, the detent, and the let-off, combined with themovable arm, and its ear and screw or projection to act upon and turnthe detent and the let-off, substantially as described.

2. In a button-setting apparatus, the staplechute, the bar d, and itsattached slotted guide (Z, provided with the saddle astride of which thestaple passes as it leaves the chute, combined with. the spring to actupon the eye of the button, substantially as described.
